fix(fusion_accounting_reports): expose dynamic OWL reports as menu items

User reported that after Enterprise uninstall, clicking 'Reports' opened
PDF statements instead of the dynamic Fusion report viewer. Root cause:
the OWL ReportViewer (registered as view_type='fusion_reports') was only
reachable via the period-picker WIZARD; no menu items used the OWL view
directly. Plus the JS service ignored report_code, so even within the
viewer, all PnL-typed reports rendered the canonical P&L line_specs.

Changes:

JS layer
- reports_service.js: runReport now accepts and forwards reportCode;
  state tracks currentReportCode so re-runs after period/comparison
  changes preserve the variant.
- report_viewer.js: reads default_report_code (and default_comparison)
  from the action context.
- period_filter.js: passes the cached reportCode on date changes;
  clears it when the user picks a different report_type.

Backend
- New fusion_accounting_reports/views/report_actions.xml with 11
  dedicated ir.actions.act_window records, one per built-in report
  (P&L, Balance Sheet, Trial Balance, GL, Cash Flow, Executive Summary,
  Annual Statements, Aged Receivable, Aged Payable, Partner Ledger,
  Tax Summary). Each opens view_mode='fusion_reports' with the
  appropriate default_report_type + default_report_code context.
- views/menu_views.xml: each report now gets its own menu item
  directly under Accounting > Reporting (sequence 10-40), matching
  Enterprise's flat structure. Custom Period wizard, XLSX export and
  Anomaly browser collected under a 'Tools' sub-group at the bottom.
- fusion_accounting_l10n_ca: adds menu items for 'Profit and Loss
  (Canada)' and 'Balance Sheet (Canada)' as siblings, plus a 'Tax
  Returns (CA)' configuration menu.

Verified live on westin-v19:
- pnl rendering 3 rows, cash_flow 9, executive_summary 7,
  annual_statements 5, ca_profit_loss 9 \u2014 each report now renders
  its own line_specs correctly.
- Reporting menu shows 14 Fusion report entries + Tools group.
- 136/136 reports + l10n_ca tests pass.

Version bumps: reports 19.0.1.1.1, l10n_ca 19.0.1.1.0.
